Abstract

본 발명은 선국된 주화면위에 부화면을 순차적으로 디스플레이하는 텔레비젼 수상기의 자동선국장치에 관한 것으로, 주화면 채널을 선국하는 제1튜너와 부화면의 채널을 선국하는 제2튜너를 구비한 텔레비젼의 자동선국장치에 있어서; 방송채널을 선국하기 위한 동작제어신호를 인가하는 제어신호 인가부; 제어신호 인가부를 통해 자동선국 제어신호가 인가되면, 선국 가능한 모든 채널이 선국되도록 상기 제2튜너를 제어하는 시트엠 제어부; 자동선국모드시, 시스템 제어부에 의해 제어되어 제2튜너를 통해 선국된 채널의 화상데이터를 정지화상으로 저장하고, 저장된 정지화상을 독출하는 메모리; 시스템 제어부에 의해 제어되어 상기 메모리로부터 독출된 정지화상을 주화면과 혼합하여 디스플레이되도록 처리하는 영상신호 혼합부를 포함하도록 구성된다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic tuning apparatus for a television receiver that sequentially displays a sub-screen on a selected main screen. The present invention relates to a television set having a first tuner for tuning a main screen channel and a second tuner for tuning a sub-screen channel. In the automatic tuning device; A control signal applying unit for applying an operation control signal for tuning a broadcast channel; A seat M controller which controls the second tuner so that all tuneable channels are tuned when an automatic tuning control signal is applied through a control signal applying unit; A memory controlled by the system control unit in the automatic tuning mode, storing image data of the channel tuned through the second tuner as a still picture and reading out the stored still picture; And a video signal mixing unit which is controlled by a system control unit and processes the still image read out from the memory to be displayed by being mixed with the main screen.
